Variation in temperature and light but not salinity invokes antioxidant enzyme activities in germinating seeds of Salsola drummondii
Published 2016“…We therefore studied lipid peroxidation and antioxidant responses of a leaf-succulent halophyte Salsola drummondii during seed germination under different salinity levels (0, 200 and 800 mM NaCl), temperature (10/20, 20/30 and 25/35°C) and light regimes. Seeds absorbed water and germinated in less than 1 h in non-saline control while increases in salinity decreased the rate of water uptake as well as seed germination. …”

Improvement of both lipid and biomass productivities of Qatar Chlorocystis isolate for biodiesel production and food security
Published 2018“…Several strategies were developed to modulate and improve algae metabolites production to meet the requirements for biodiesel production. Most previous research evidenced that the increase of the lipid content is accompanied by a decrease of the biomass production, which increases the cost of the downstream processing. …”
